i Y ELECTRIC BATTERY'l SPECIFICATIONformng part of Letters Patent No. 700,497, dated May 20, 1902.

Original application filed August 9.21900, Serial No. 2 6 ,397. Divided and this To all whom, t may concern):

Be it known that I, CONRAD HUBERT, a citizen of the United States of America',and a resident of New York city, borough of Manhattan, in the county and State of NewYork, have invented certain new and useful Improvements in Electric Batteries, of which the'following isa specification. l

. My invention relates to certain improvements in battery-cells, such as are especially adapted for use in connection with the form of casing described and claimed in another application filed byV me in the United States Patent Office on the 9th day'of August, 1900, and serially numbered 26,397,frimprove ments in electric lamps, of-wh-ich said previous application my present application is a division, made in pursuance of requirements of the Commissioner of Patents.

' My invention consists inthe construction and arrangement of the several parts of a battery-cell, as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which form a part of this application and in f which corresponding parts are designated by corresponding' marks of reference, Figure l is a side elevation of a battery-cell constructed'in accordance with this invention. Fig. 2 is a central vertical section thereof. Fig. 3 is a plan view of the head of a cell. l

As shown, my improved cell consists4 of a cylindrical cup a, the cup itself forming by preference one of the elements of the celland inclosing the centrally-located and opposite element b and the electrolyte c. In the precise construction used by me the cup a is of zinc and the centrally-located element b of carbon, the top of the cell beingclosed by a layer of insulating-cement CZ. A ianged'annulus of good conducting material, such as copper or brass, is soldered to the head of the cup-shaped element a and has its upper surface approximately iiush with a metallic button f on the head of the central element b, the annulus and button being exposed above the cement.

' The particular material of which the several parts hereinbefore referred to are constructed is not essential to my invention,

application filed April l 1**901. Serial (No model.) Y

said previous application, Serial No. 26,397.

For the purpose of more clearly bringing out the result thus obtained I have in several iigures of my drawings shown in 'dotted lines a casing having proper contacts for accomplishing the ends above set forth. Thus in Fig. 1 I

have shown a suitable casing gin the form of a cylinder, provided with a removable top h,

the top carrying a centrally-'disposed contactpoint 1J and an eccentrically-disposed contactpoint 1c, the distance of the contact-point lo from the contact-point 1I being substantially equal to the radial distancebetween the annulus @and themetallic'button f of the cell,

the central contact e' will rest upon the button f and the eccentric contact la will rest v upon the annulus e. Owing to the annular shape of the part e the connection between it and the eccentric contact lc will be made with- -out regard to the rotation of the cell and cover in respect to each other and to the casing.

Itistherefore possible with `my improved construction of cell to connect a cell in a casthecell, vshould of course be insulated from the point k and the other element of the cell except4 through the connection made by the external'circuit, the parts 'i and k being con- 'nectedto thevopposite leads thereof. Thus in the form of casing shown in the drawings if the cylinder and top be of metal the contact-points may be supported, as shown, by an insulating-strip h. (See Fig. 2.) l f ing with great ease and rapidity. The contact-point rl, corresponding to one element of ILdo not in this application make any claim to the construction of thecasi'ng or the arrangement of the contactpoints'therein,as such matter is claimed ininy originallapplication, Serial No. 26,397, of which this isa division; but

What I do claim is v 1. As a new and improved article of manufacture the hereinbefore-described battery- 7o whereby when the cover is placed upon a cell cell having two elements, and having a centrally-disposed contact-point and a surrounding annulus upon one end thereof, substantially ush With each other and connected respectively With the several elements, the contact-point and annulus forming terminals of the respective elements of the cell, substantially as described.

2. As a new and improved article of manufacture, the hereinbefore-described batterycell consisting of two elements, one element being centrally located and the other element surrounding the first-named element and being concentric thereto, and a button and a surrounding annulus,substantially ush with each other, and connected to the central and concentric elements respectively, substantially as described.

3. As a new and improved article of n1anufacture, the hereinbefore-described batterycell, consisting ofa cup-shaped cell forming one element of the battery and inclosing another element centrally located therein, the

which it is separated, substantially as described.

4. The hereinbefore-described battery-cell having tWo elements, and having upon one end thereof a centrally-disposed point and a surrounding annulus, substantially as described, connected respectively to the several elements of the cell, the point and annulus forming terminals of the respective elements of the cells and being adapted to bear upon terminals of an external circuit, and to electrically connect the elements of the cell therewith, as and for the purpose set forth.

5. As a new and improved article of manufacture, the hereinbefore-described battery cell with positive and negative elements, having a centrally-disposed contact-point'and a surrounding contaot-plate upon one end thereof,the surrounding contact-platebeing formed by an annulus, the central point and the surrounding annulus being connected one to the positive and the other to the negative element of the cell, and forming terminals of the said elements, substantially as described.
